gopro hero 2

GoPros are great action cameras for snagging photos and videos places where you can’t normally bring real camera gear. The problem is, even with the waterproof GoPro case for the Hero 2 — the underwater videos tend to be blurry and out of focus. Unsatisfied with his videos, [Mitchell] decided to make his own lens for the case!

The waterproof case has a removable concave lens, but for whatever reason it’s not very good underwater. Lucky for [Mitchell], it’s quite easily removed with 6 screws, revealing a nice thick gasket and the lens. Instead of trying to go fancy with some glass element from a broken camera, he’s just taken some 1/4″ plexiglass and cut out a piece to fit the case. It was a bit too thick for the original configuration, so he’s actually flipped the retaining ring upside down to space the lens away from the actual camera. A bunch of silicone later and the case is waterproof again with a new lens!

The resulting footage with the new lens looks awesome underwater — take a peek after the break.
